This is a continuation of U.S. Provisional Application No. 60/461,357, filed Apr. 8, 2003.

FIELD OF THE INVENTION

The present invention is directed to a new and improved tool or implement holder, such as for a razor, employing a semi-rigid or flexible tube containing a composition, such as shaving cream, that works in association with the tool or implement, such as a razor blade attachment at the end of the tube which can receive and detachably secure a razor blade. The body of the tube serves as a handle for the tool or implement.

BACKGROUND OF THE INVENTION

There are many implements or tools used today that are used in association with a composition; and there are many compositions in use today that require or are preferably used with a tool or implement. For example, depilatories are normally used in conjunction with a scraper. Depilatory composition is applied to the area of interest, the depilatory composition is allowed to set for a set period of time, and then the composition, together with the depilated hair, is removed employing a scraper. Similarly, compositions used to clean spots off of clothes or off fabrics or from rugs are applied to the soiled area, allowed to work in the soiled area to perform their action, and frequently the composition is worked into or rubbed in, or rubbed with a brush before removal to enhance cleaning. Grouting compositions that are used to grout cracks or holes in surfaces, such as walls or ceilings, are applied to fill the crack or hole and then a blade is applied to smooth the grout so that it is even with the surface surrounding the hole or crack. Massage lotions are applied to the skin and then the massaging implement is worked over the skin with the lotion acting as a lubricant as well as performing other functions depending upon the composition of the lotion. Compositions are available for removing paint from surfaces, such as mirrors and windows. Compositions are available to soften materials to remove labels, and the like. The softening composition is applied to the surface of the material or to the label to act upon it, the composition is allowed to work on the material for a period of time, and then it is scraped off employing a planar scraper blade which can have a knife-edge or blunt edge with sharp 90-degree corners.

Paint, ink, coatings, waxes, and protective coatings are applied to an area frequently using a sponge. Some paint removers and polishers are applied to a surface and then after they have acted upon the surface, they are rubbed with sandpaper or a very fine polishing surface to either remove the paint or coating or to polish the surface.

Razors have traditionally comprised a frame with a fixed razor blade or a razor blade holder which is used to removably secure razor blades. Razors have been in use for over a century. The handle is normally elongated and shaped somewhat like a toothbrush handle. The head of the razors for replaceable razor blades is adapted to receive the particular type of razor blade that it is designed for. Although there are razor blades that can be received on a universal head, many razor blades can only be received on a proprietary head.

Shaving lotions come in cans, flexible tubes, semi-rigid tubes and in soap cakes. Shaving lather is normally applied to the skin when the skin is wetted. Preferably the skin has been prewashed to remove facial oils and bacteria. Earliest shaving lathers were lathered up from soft caked soap placed in the bottom of a mug, wetted with water and then lathered up with a brush. The brush applied the lather to the face. Shaving lather caked soap is still available. In the 1930's, prepared lather creams started to appear. These lather creams were sold in flexible tubes, tubes similar to toothpaste tubes. The tubes were originally made from tin or lead or alloys thereof. Later tubes were made of aluminum. Today the tubes are made from plastic. Some lather creams were meant to be applied to a wet face directly with the hands or fingers. Other lather creams were made to be applied with a brush. These types of shaving lather creams are still available. In the 1960's, shaving foams became available in pressurized cans wherein the lather foam was released from the can by pressing the relief valve. The lather foam was released as a foaming mass which was applied to the face typically with the fingers and hands. This is the most common form of shaving lather used today.

With regard to volume and size, the cake soap shaving lather requires less room, but it also requires a container, such as a mug, and a brush to utilize. Volumetrically, the shaving lathers that are available in aerosol cans require the most space and can be applied with the hands and fingers making them easy to use. Shaving lather creams available in tubes are easy to apply with the hands and fingers and require less than half the space of shaving lathers supplied in aerosol cans and work equally as well. They do not require a mug or brush.

Many women prefer to shave body hair in the bathtub or in the shower, and many men prefer to shave their beards in the shower. The bath and shower are not convenient for the use of the cake soap shaving lather with mug and brush. If the mug is dropped, it can break since they are normally made of ceramic material showering sharp particles. In addition, the mug can chip the bathtub or shower tile The aerosol can has a disadvantage that if it is kept in the shower or around the tub, it gets wet and the metal of the aerosol rust causing rust stains in tile grout and the like. In addition, if the can is dropped, it can chip the bathtub or shower tile. Thus, when shaving in the bathtub or in the shower, shaving lather cream that is contained within a flexible tube is preferred because a flexible tube is normally nonmetallic and can be dropped without breakage or chipping and can be left in or around the tub or shower without causing rust stains. The flexible tube of shaving cream is more convenient for travel because it requires less space than aerosol cans and does not require the use of a mug or brush for application.

One of the problems that is encountered by people when traveling is the amount of space required for their shaving gear including the razor blade with its frame and the shaving lather source, whether it is soap cake shaving lather applied with a brush or shaving lather applied from a flexible tube or shaving lather applied from an aerosol can. Another problem is that when people shave around the bathtub or shower, the separate components, the razor blade with handle and the source of the shaving cream, take up space which is normally in a premium around a bathtub or in a shower stall.

Thus, there is a need and there has been a need for a single unit shaving device which contains the shaving lather as well as functioning as a frame, support and handle for the razor blade.

Many compositions, such as shaving cream, cleaning preparations, and the like, are thick or gelatinous materials that cannot easily be removed from a rigid bottle. These compositions are more easily applied from a flexible container having flexible or semi-rigid walls, such as a toothpaste tube.

Many compositions are supplied in flexible tubes with a separate tool or implement for use. The tube and tool or implement frequently get separated, and thus when the user wants to use the composition, they cannot find the implement or tool or vice versa. In addition, because of the relatively low cost for many compositions, tools are made cheaply and skimpily and do not have an adequate handle. It is an object of the present invention to provide a flexible tube having flexible or semi-rigid walls for dispensing a composition for use and the implement or tools being secured to the flexible tube so that the implement or tool cannot be separated from the composition and the flexible tube can function as a large handle so that the implement or tool can be comfortably held and worked.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-8, the razor blade attachment unit 10 comprises a frame 12 having an arm 14 extending upwardly and outwardly therefrom and a razor blade attachment plate 16 secured to the end of the arm 14. Alternatively, a proprietary razor blade attachment assembly can be used (not shown). The razor blade attachment plate 16 can be a universal attachment plate which will receive most razor blades manufactured today. However, some razor blades cannot be secured by the universal attachment plate and the proprietary attachment assembly must be used for the attachment of such blades if they are to be used.

The frame 12 has a ribbed front side 20 and a planar back side 22. A hole 24 extends through the frame from the ribbed front side to the planar back side adapted to receive a hanger to support the razor or a fastener, such as a rivet, to secure the frame to the sealed end or flexible tube. The ribbed front side 20 has a pair of U-shaped ribs 28R and 28L on the right side and left side, respectively, of the frame that extend downwardly from the outer ends of the arm to the bottom of the frame where they curve in a U-shaped manner and extend upwardly again where they join to form a platform 32 which is connected to the arm 14. The frame 12 has a planar wall 18 which is recessed with respect to the front of the U-shaped ribs. The back side of the planar wall 18 defines the planar back side 22. On the planar back side 22 at the base 23 of the frame 12, the surface of the back side is cut inwardly to form an arcuate scalloped wall portion 26. This portion is scalloped to receive the bulging wall of the shaving cream semi-rigid tube. The use of the ribs in conjunction with the planar wall provides a frame that is strong and light weight and minimizes the use of materials and is yet rigid enough to perform the desired function.

To both reinforce the razor blade attachment unit 10 and to add a decorative feature to the unit, portions of the U-shaped ribs are stiffened and reinforced with respect to each other by the platform 32 and with a series of arcuate ribs 30A through 30D. At the base of the frame 12, a base rib 34 extends from the base of the U-shaped ribs to further stiffen and reinforce the unit. The frame 12 is relatively rigid or stiff because of the planar wall 18, the U-shaped ribs 28R and 28L, and arcuate ribs 30A through 30D, and the base rib 34. The arm 14, being a curved sheet-like structure has a limited degree of flexibility to assist the attached razor blade (see FIG. 6) to follow the contour of the skin during shaving.

Referring to FIGS. 9 and 10, the razor blade of the present invention comprises the razor blade attachment unit 10 and the semi-rigid tube 112. The flexible or semi-rigid tube 112 conveniently contains shaving cream which can be forced out of the flexible tube through the applicator head 114. The shaving cream can be applied to the face employing the applicator head. This eliminates the need to use the hands or fingers for application of the shaving cream. The applicator heads are described in U.S. Pat. Nos. 5,871,020 and 6,053,184, the disclosures for which are incorporated herein by reference. The invention is not limited to flexible tubes having applicator heads. Flexible tubes with conventional heads, such as seen on toothpaste tubes, shaving cream tubes, etc., can be used. The end of the flexible or semi-rigid tube 112 is sealed to form an end seal 118. The end seal can be arcuate as seen in FIG. 9 and adapted to mate with arcuate scallop wall portion 26 of razor blade attachment unit 10. However, the end seal can also be nonarcuate, that is straight, as seen in FIG. 47. This is adapted to mate with a nonarcuate or straight scallop wall portion 26A seen in FIGS. 13, 18, 21, 24, 26, 29, 31, 34, 36, 39, 41, and 45. The end seal is conveniently sealed by sonic welding although heat welding, plasma welding or suitable adhesives can also be used. The planar back side 22 of the razor attachment unit 10 is secured to the end seal 118 of the semi-rigid tube 112 in the attachment area 122 (shown in cross hatching in FIGS. 9 and 47) by sonic welding, heat welding, plasma welding an adhesive, or by a rivet passing through the hole 124 and a hole 126 in registration with hole 124. Sonic welding has been found to be quite satisfactory. The bulge of the flexible tube adjacent to the seal end 118 is accommodated in the scallop wall portion 26 (26A in FIG. 47) of the razor blade attachment unit 10 which permits the planar back side 22 of the razor blade attachment unit 10 to be somewhat in plane or somewhat parallel with the longitudinal axis of the semi-rigid tube 112. This positions the razor blade attachment plate 16 and the razor blade received therein correctly with respect to the semi-rigid tube handle 112. The angle A is preferably about 25°±5°. Although the scallop wall portion can be secured to the outer wall of the flexible tube, it has not been found necessary by the applicant and such attachment is optional. The hole 24 extends through the razor blade attachment unit 10 as described above and through the hole 126 in the head portion 120 and the end seal 118. This hole can be utilized for hanging the razor 110 on hooks in retail establishments for display and presentation for purchase, or it can receive a rivet or other securing attachment to secure the unit 10 to the flexible tube 112.

Although it is anticipated that the unit will be sold with a razor blade attached, the razor can be sold and transported or stored without a razor blade secured to the razor blade attachment plate 16. When the razor is to be utilized, a razor blade 40 can be slide on to the plate 16 in the conventional manner. The plate can be designed to detachably lock and secure the razor blade 40 on to the plate. When an operator wishes to replace the razor blade, take the razor blade out for any reason, the razor blade 40 can be slid off the plate 16. The attachment plate 16 can also be designed to permanently receive a razor blade which would prevent removal of the razor blade from the plate 16. In the razor blade illustrated in FIG. 6, the razor blade has three blades 42. Some razor blades have a single blade, others have two or more blades, and they can also be utilized on the present razor 110.

Referring to FIG. 11, another embodiment of the razor of the present invention is illustrated. The elements of this embodiment, which are identical to the elements of the razor shown in FIGS. 9 and 10, have the same drawing numbering. The razor attachment 10E has a front wall 21 extending from the frame 12B and a slot 27 is formed between the back wall 19 and the front wall 21. The slot 27 is adapted to securely receive the sealed end 118 of the flexible tube 112 in a friction fit or pinch fit. The walls of the slot 27 can have protrusions or teeth (not shown) to firmly grip the sealed end 118 to prevent the razor attachment unit 10 from being removed from the flexible tube 112. Additionally, the razor attachment unit can be secured to the sealed end by sonic welding, heat welding, plasma welding, or adhesive between the walls of the slot and the sealed end, or by a rivet passing through the hole 124 and a hole 126 in the sealed end which is in registration with hole 124.

Referring to FIGS. 12-16, another alternative embodiment of the razor attachment unit 10A is illustrated. The elements of the razor attachment unit 10A which are identical to the elements of razor attachment unit 10 are shown with the same drawing numbers. The principal difference between the razor attachment unit 10A from that of razor attachment unit 10 is the addition of the extended braces or supports 50 which extend down from the front of the frame 12A to provide further support of the razor attachment unit with respect to the flexible tube 112 (see FIG. 10). When force is applied to the razor attachment 16, such as during shaving, the attachment between unit 10 and the sealed end 118 acts as a pivot point and the arm between the point of attachment and the razor attachment head 16 acts as a fulcrum or lever arm which forces the bottom portion of the frame 12 against the side of the flexible or semi-rigid tube 112 which could collapse the side of the tube which could render the tube's effectiveness as a tool handle. The braces or support 50 of the razor attachment unit 10 FIGS. 12-16 increases the surface area of the bottom portion of the frame 12A and braces the frame and resists pivoting of the frame at the point of attachment of the frame and the sealed end, and forcing the bottom of the frame into the side of the tube.

The flexible tubes 112 are made of plastic such as polyethylene and polypropylene. The flexible tubes can be co-extruded tubes which are multilayered tubes made of plastic and/or meal. These tubes can be made in a variety of flexibilities from being very flexible to being semi-rigid. In fact, they can be made quite rigid. But rigid wall tubes are undesirable because they can make it difficult, if not impossible, to dispense the contents therein, especially for thick compositions. Thus, it is anticipated that the attachment will be used on either flexible or semi-rigid tubes. For flexible wall tubes, the movement or pivoting of the razor attachment unit with respect to the sealed end is a minor problem when the tube is filled with content. However, when a third or more of the contents have been evacuated from the tube, the razor attachment unit with sufficient force can partially or fully collapse the side of the tube as the unit pivots at the point of attachment as the razor is used. The razor attachment unit 10A has less of a tendency to pivot and collapse the side of the tube than the razor attachment unit 10 when used on a partially filled flexible tube.

Referring to FIGS. 17-19, the attachment unit can be designed for a variety of purposes. The unit shown in FIGS. 17-19 is a cosmetic scraper attachment unit used for scraping surfaces. The scraper head 16A will be integral with the scraper attachment unit 10B. The scraper head 16A can have a blunt edge or a knife-edge edge or an edge in between. The components or elements of scraper attachment unit 10B, which are identical to the same elements in razor attachment unit 10, are identified with the same drawing numbers. The scraper head 16A can be utilized for a number of applications. It is contemplated using the scraper attachment unit 10B with a tube 112 containing a depilatory agent for removal of hair from the body. The depilatory agent will be applied to the surface of the skin which bears the unwanted hair, allowed to work depilate the hair and then the composition and the depilated hair will be removed by employing the scraper to scrape off the composition and the depilated hair. After the operation is complete, hair and composition adhering to the scraper head 16A can be easily removed with water to leave a clean scraper attachment unit. The resiliency of the neck 14A can be adjusted either in thickness and/or in the composition used to manufacture the scraper attachment unit so that the semi-rigid neck that has sufficient resiliency so that the scraper head rides over imperfections on the surface of the skin.

Referring to FIGS. 20-22, a planar blade attachment unit 10C is illustrated. The elements of the blade attachment unit 10C and the razor attachment unit 10, which are identical, have been identified by the same drawing numbers. With proper design and manufacture, the blade attachment unit 10C can be utilized as a scraper or a grouting blade 52. When the blade 10C is to be utilized as a grouting blade, the blade 52 will be relatively pliable or flexible and normally will have a blunt squared-off edge 53. When blade 10C is a grouting blade, it can be utilized to apply grout or filler from the flexible tube to cracks, holes and the like. When the blade 10C is to be utilized as a scraper, such as a scraper to remove paint or other materials, blade 52 will be relatively rigid and the edge 53 will be a sharp edge, like a knife-edge, or a squared-off edge 53 with sharp edges and corners. When blade attachment unit 12C is a grouting blade, the grout will be stored within the flexible tube. In use, the grouting material will be dispensed from the tube into the crack or hole and the grouting material will be forced into the crack or hole and smoothed with respect to the surface surrounding the crack or hole employing the grouting blade 52. When the blade attachment unit 12C is a scraper, the flexible tube will contain composition used to soften, lift or remove material, such as paint, label adhesive, tar, and the like. The composition will be dispensed from the tube onto the material that is to be softened or removed. The composition is given sufficient time to work on the material, then the material is scraped off employing the scraper blade 52. The scrapers are illustrated with working ends perpendicular to the longitudinal axis of the blade. The working edge can be angled 53A (in phantom FIG. 20) to the longitudinal axis of the blade.

Referring to FIGS. 23-27, a brush attachment unit 10B is illustrated. The elements of the brush attachment unit 10B, which are common with the razor attachment unit 10, are identified by the same figure numbers. The brush attachment unit 10B has a bristle support plate 56 on which bristles 54 are supported. The bristles support plate 56 is connected to the frame 12C by the rigid neck 14C. The bristles can be molded into or with the bristle support plate at the same time the brush attachment unit frame is molded, or they can be added later. The bristles can be plastic, fiber, metal, or the like. In one embodiment, the bristles and bristles support plate 56 are manufactured separately and secured to the neck 14C by sonic welding, heat welding, adhesive, or the like. The bristles can be stiff or they can be flexible, depending upon the intended use of the brush attachment unit.

Referring to FIGS. 43-47, a universal implement attachment unit 210 for flexible tubes is illustrated. The elements of the attachment unit 210, which are identical to the elements of the razor attachment unit 10, are illustrated with the same drawing numbers. The attachment unit 210 has a top portion 258 with a female receptacle 266 which is adapted to receive the male extension 264 of the implement 262. The female receptacle 266 receive the male extension 264 either in a permanent locked position or in a removable secured position depending upon the intent of the user. The tool can be any of the implements shown in the preceding figures, including a razor attachment, a scraper, a blade, a brush, massager, a sponge applicator, a sandpaper/polishing pad, and the like. The tool can be received by the attachment unit 210 by securing the male extension 264 of the tool implement 262 into the female receptacle 266 of the attachment unit 210. The working end of the implement can be a razor attachment, a blade, a cosmetic scraper, a brush, massager, sandpaper/polishing pad, and the like.

As discussed above, the razor blade attachment plate is offset 25 degrees plus/minus 5 degrees to the longitudinal axis of the flexible tube (FIGS. 10-11). The cosmetic scraper is offset 30-90 degrees with respect to the main plane MP of the attachment unit and/or the longitudinal axis LA of the flexible tube. The sealed end of the tube is planar and lies in or is parallel to the longitudinal axis of the flexible tube. The planar backside 22 of the frame 12 is normally parallel to or intersected by the longitudinal axis of the flexible tube since the planar backside is secured to the sealed end. The planar scraper blade and the planar grouting blade FIGS. 20-22 are roughly parallel with respect to the main plane MP of the attachment unit 10C and/or intersects or is parallel to the longitudinal axis LA of the flexible tube. Although the planar blade tool is normally planar with respect to the longitudinal axis of the flexible tube, the blade can be offset from the longitudinal axis LA, such as angled out 45 degrees if so desired. The support plates for the attachment units 10D, 10F, 10G, and 10H are normally offset around 45 degrees plus/minus 15 degrees from the main plane MP and/or longitudinal axis LA. That is, a perpendicular axis PA passing through the support plate (see FIG. 25) is 45 degrees to the longitudinal axis LA of the flexible tube and/or the main plane MP of the frame plus/minus 15 degrees. However, the support plate can be perpendicular to the longitudinal axis LA of the flexible tube or the main plane MP of the frame depending upon the tool and how it is most effectively used.

As discussed above, the attachment units can be fixed to, or secured to, the sealed end of the flexible tube with welding (heat or sonic) forming a weldment boundary between the sealed end and the attachment unit, or with an adhesive or cement capable of bonding the attachment unit to the sealed end forming an adhesive or bonding film or layer between the sealed end and the attachment unit, or by a fastener[s] such as a rivet.
